Abstract (en)

[origin: DE19826520C1] The invention relates to a method for controlling heat transfer on a work piece during condensation soldering. According to said process, a work piece placed in a vapour phase is first rapidly heated to a predetermined temperature, and then temperature is controlled by changing the vapour volume on the work piece surface. Preferably, a work piece in the vapour phase is heated to a temperature lower than the melting point of the filler metal, and then the work piece is heated more slowly to the melting point of the filler metal relatively to the vapour free space, at the boundary of the vapour phase. This invention is advantageous in that it provides a method of rapid condensation soldering with no undesirable side effect such as formation of solder pearls.
